QSC Audio ISA 500T Manuel D’Utilisation

Use four screws and washers when mounting the
ISA amplifier to the front rails. Support the weight
of the amplifier while securing it to the rails to
avoid bending or distorting the front rack mount
ears.

Method 2- The amplifier is first
installed from the front of the
rack. Then, the accessory rear
ears are positioned on the rear
rack rails and secured.  The pin
installation position can now be
selected. Install the pin so that it
fits well into the slot provided on
the amplifier's rear mounting
tab.

Method 1- The amplifier is first
installed from the front of the
rack and then the ears are
secured directly to the amplifier
with two machine screws as
shown, left. Then the ears are
secured to the rails using
ordinary rail hardware.

Supporting the amplifier at the rear is extremely
important, especially for mobile and portable use.
Equipment is often installed in racks at a remote
location, then later transported to the installation
site. During transport, the shock loads encoun-
tered on the chassis and rack can easily damage
an unsupported amplifier and the rack rails.
Unless the amplifier is being installed in its final,
fixed location, we strongly recommend supporting
the rear of the amplifier.

Rear rack mounting ear kits are an accessory item
and are available from QSC’s Technical Services
Department or from your dealer or distributor.

The rear rack mounting ear kit may be installed in
two different ways. Refer to the literature
included with the rack mounting ear kit for up-to-
date information. The basic information is
supplied here to give you an idea of how the
accessory rack mounting ears are used.
